INTRODUCTION
WHAT IS WIRELESS ?
The word wireless is dictionary defined “having no wires ” .
In networking terminology , wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and or microwaves to maintain communications.
1G TECHNOLOGY
1G refers to the first generation of wireless telephone technology, mobile telecommunications which was first introduced in 1980s and completed in early 1990s.
It's Speed was upto 2.4kbps.
It allows the voice calls in 1 country.
1G network use Analog Signal.
DRAWBACKS OF 1G
Poor Voice Quality
Poor Battery Life
Large Phone Size
No Security
Limited Capacity
Analog Signal
1G Wireless System
2G TECHNOLOGY
2G technology refers to the 2nd generation which is based on GSM. It was launched in Finland in the year 1991. 2G network use digital signals. It’s data speed was upto 64kbps.
Features Includes:
It enables services such as text messages, picture messages and MMS (multi media message).
It provides better quality and capacity .
DRAWBACKS OF 2G
2G requires strong digital signals
to help mobile phones work. If there
is no network coverage in any specific
area , digital signals would weak.
These systems are unable to
handle complex data such as Videos. 2G Wireless System

2.5G TECHNOLOGY
2.5G is a technology between the second (2G) and third (3G) generation of mobile telephony. 2.5G is sometimes described as 2G Cellular Technology combined with GPRS.
Features Includes: Phone Calls Send/Receive E-mail Messages Web Browsing Speed : 64-144 kbps Camera Phones Take a time of 6-9 mins. to download a 4 MB Mp3 song.
3G TECHNOLOGY
3G technology refer to third generation which was introduced in year 2001.
Data Transmission speed increased from 144kbps- 2Mbps.
Typically called Smart Phones
FEATURES OF 3G TECHNOLOGY
Providing Faster Communication
Send/Receive Large Email Messages
High Speed Web / More Security
Mobile TV/ Phone Calls
Large Capacities
11 sec – 1.5 min. time to download a 4 MB Mp3 song.
4G TECHNOLOGY)
4G TECHNOLOGY)
4G technology refer to or short name of fourth Generation which was started from late 2000s.
Capable of providing 100Mbps – 1Gbps speed. High Security Provide any kind of service at any time as per user
requirements, anywhere.
Features Include: More Security High Speed High Capacity
DRAWBACKS OF 4G
Battery uses is more
Hard to implement
Need complicated hardware
Expensive equipment required to implement next generation network.
3G WIRELESS SYSTEM 4G WIRELESS SYSTEM
WIRLESS MODELS OF 3G & 4G
5G TECHNOLOGY
5G technology refer to short name of fifth Generation which was started from late 2010s.
Complete wireless communication with almost no limitations.
It is highly supportable to WWWW (Wireless World Wide Web).
BENEFITS OF 5G TECHNOLOGY
High Speed, High Capacity 5G technology providing large broadcasting of data in Gbps . Multi - Media Newspapers, watch T.V programs with the
clarity as to that of an HD Quality.
Faster data transmission that of the previous generations.
Large Phone Memory, Dialing Speed, clarity in Audio/Video.
Support interactive multimedia , voice, streaming video, Internet and other
5G is More Effective and More Attractive.
EVOLUTION OF 1G TO 5G TECHNOLOGY
WIRELESS APPLICATIONS
Wireless applications are those which we use free space as the transmission medium & do not involve cabling like fibre or copper cables.
Wireless solution for:
Business and Industry
Schools , Colleges
Doctors , Pilots
Police and Vehicles etc.
WIRELESS SERVICES
CONCLUSION
All totally the best way to help all users is to use 5G as the next wireless system and in totally it is safety and secure for public, this the need that demands the solution.
Today’s wired society is going wireless and 5G is leading this .
5G technology is going to give tough competition to Computers and Laptops.
It will be available in the market 2020 at affordable cost with more reliability than previous mobiles.
